屏蔽泵型號(hào),屏蔽泵結(jié)構(gòu),屏蔽泵結(jié)構(gòu)圖
屏蔽泵結(jié)構(gòu)通常按泵冷卻潤(rùn)滑循環(huán)回路的形式定義。屏蔽泵型號(hào)按照不同的結(jié)構(gòu)也分為多種。
一、屏蔽泵結(jié)構(gòu)及屏蔽泵結(jié)構(gòu)圖
1、正循環(huán)屏蔽泵結(jié)構(gòu)
屏蔽泵正循環(huán)結(jié)構(gòu)也稱基本型結(jié)構(gòu)或稱普通型結(jié)構(gòu)，如圖15-2所示，從泵體出口法蘭處設(shè)置引液管引入冷卻液，這種臥式屏蔽泵結(jié)構(gòu)用于輸送一般性非易汽化介質(zhì)。
當(dāng)輸送易汽化介質(zhì)時(shí)，冷卻液經(jīng)后導(dǎo)軸承、屏蔽套、前導(dǎo)軸承回到葉輪進(jìn)口，冷卻液的溫度由低變高，部分冷卻液可能已汽化產(chǎn)生氣泡，帶氣泡的介質(zhì)進(jìn)入葉輪進(jìn)口將堵塞葉輪進(jìn)口流道，導(dǎo)致泵性能下降，嚴(yán)重時(shí)泵將出現(xiàn)斷流，冷卻液也就不能循環(huán)工作。所以，這種結(jié)構(gòu)適用于一般的非易汽化介質(zhì)的輸送。

2．逆循環(huán)屏蔽泵結(jié)構(gòu)
逆循環(huán)結(jié)構(gòu)也稱之為易汽化型結(jié)構(gòu)，如圖15—3所示，從泵腔處引入高壓流體，一部分冷卻屏蔽套、后導(dǎo)軸承后，經(jīng)循環(huán)管獨(dú)立回到泵的人口罐的氣相部；另一部分冷卻液只冷卻前導(dǎo)軸承，回到葉輪進(jìn)口，這一部分冷卻液溫升極小，不至于出現(xiàn)汽化。因此，這種結(jié)構(gòu)適用于輸送易汽化介質(zhì)。

3．獨(dú)立循環(huán)屏蔽泵結(jié)構(gòu)
獨(dú)立循環(huán)結(jié)構(gòu)屏蔽泵如圖15—4所示，獨(dú)立循環(huán)結(jié)構(gòu)也稱之為高溫型結(jié)構(gòu)。
在泵轉(zhuǎn)輔上設(shè)置一輔助葉輪4，由輔助葉輪實(shí)現(xiàn)獨(dú)立循環(huán)工作。循環(huán)液由輔助葉輪出口經(jīng)過(guò)盤(pán)管流入底部潤(rùn)滑下導(dǎo)軸承、屏蔽套以及上導(dǎo)軸承，構(gòu)成循環(huán)回路。循環(huán)液盤(pán)管外部由一冷卻水套包覆，冷卻水套設(shè)有進(jìn)出管冷卻。輸送介質(zhì)與循環(huán)回路介質(zhì)幾乎不交換，使電動(dòng)機(jī)避免高溫工作。因此，這種結(jié)構(gòu)適用于輸送高溫介質(zhì)。
獨(dú)立循環(huán)屏蔽泵結(jié)構(gòu)圖：
4．多級(jí)葉輪屏蔽泵結(jié)構(gòu)
多級(jí)葉輪屏蔽泵結(jié)構(gòu)如圖15—5所示。圖15—為臥式多級(jí)結(jié)構(gòu)，15—5b為立式多級(jí)結(jié)構(gòu)，15-5c為兩端葉輪全對(duì)稱結(jié)構(gòu)。
多級(jí)葉輪屏蔽泵的葉輪通常均分左右兩部分，葉輪背靠背，實(shí)現(xiàn)軸向力平衡。與低比轉(zhuǎn)速同參數(shù)的單級(jí)葉輪相比，多級(jí)屏蔽泵比轉(zhuǎn)速大大增加，從而提高了泵的效率。許多高揚(yáng)程參數(shù)采用單級(jí)葉輪是無(wú)法實(shí)現(xiàn)的。
雙級(jí)葉輪全對(duì)稱屏蔽泵，屏蔽電動(dòng)機(jī)左右軸端各設(shè)置一個(gè)葉輪，轉(zhuǎn)子幾乎沒(méi)有軸向力，泵運(yùn)行平穩(wěn)、可靠。

5．微型屏蔽泵結(jié)構(gòu)
圖15—6所示是一種微型屏蔽泵。微型屏蔽電動(dòng)機(jī)有單相、三相兩種。微型屏蔽泵定子屏蔽套役有和定子焊死，是通過(guò)平墊壓緊的可拆結(jié)構(gòu)。轉(zhuǎn)軸是空心軸，循環(huán)液流經(jīng)屏蔽套從軸中心孔回到葉輪人口。該泵適用于家庭供水、增壓等。國(guó)內(nèi)生產(chǎn)的微型屏蔽泵大量出口到國(guó)外。
